Abstract
A video signal processing and distribution apparatus receives a cable television signal which includes a plurality of television channels. The cable television signal is transferred through one or more band block filters, each of which can block a particular channel from the cable television signal. An oscillator is provided for each local video signal that is desired to be added into the cable television signal. Each oscillator produces a carrier signal within the band of a removed television channel. The local video signal modulates the carrier signal to produce a new channel signal that is combined with the cable signal, which has had at least one selected channel removed. The resulting modified cable signal is distributed to one or more television sets wherein each set can view a plurality of new locally generated channels which have been added to the cable television signal in place of previously existing channels.
